The chant comes from Game of Thrones, in the 2015 season five finale where Septa Unella follows Cersei Lannister on her walk of atonement through King's Landing, ringing a bell and repeating the word. The scene became one of the show's most parodied moments, clipped for reaction videos, edits and social posts whenever someone deserved public embarrassment. Its simple one word repetition made it easy to reuse without context, and it remains a shorthand for dramatically shaming a fail, a confession or a bad decision online.
